JOSEPH S. WOOD, OF' PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HIM- SELF AND JOHN J. OARBERRY, Olv SAMEl P LAOE.

Leners Patat No. 101,558, dated Apro 5, 1870.

IMPROVEMENT IN GENBRATING- HYDROG-EN AND HYDRCCARBON G-AS The Schedule referredto in these Letters Patent and making part of the same I, JOSEPH S; WQOD, of the city and county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Generating H'ydrogen and Hydrocarbon Gas,` of which the following is a specification.

The nature of my invention consists inthe construction of an apparatus with an upper and lower chamber, so connected by a pipe and stop-cock that the dilute acid, when under pressure, passes from the lower chamber into the upper one, where it can be retained by means of the stop-cock, whilst the refuse is being taken from the bottom chamber.

Also, in the manner ofpassing the basket for iron filings through both the upper and lower chambers.`

Also, in the construction and arrangement of the' device for carbureting or naphthalizing the hydrogen.

To'enable others skilled in the art to make andruse my invention,I will proceedto describe its construction and operation, reference being had to the accompanying drawings.

Figure 1 is a vertical section.

Figure 2 is a plan of the carburetor.

Figure 3 is a general-view of the hydrogen-gas maf chine and carbnreter, arranged as two distinct lmachines. l

A is the cylindrical vessel, having a partition, a', in the center, so as to dividehit into an upper and lower chamber or tank, BB.

The tank B is open to the air at the top, but covered with a lid, C, removable, so that the tank B can be filled with water and acid, and-its temperature and density easily tested.

From the bottom ofthe tank B passes the pipe M, having a stop-cock, vN, upon it, and connecting with the lowertauk B' at a lower level than the bottom of the basket G.

The division-plate a' has a central hole, to which is brazed the pipe D, passing out through the lid O, and closed with a tight cap, E, screwed on.

Within this tube is inserted the basket G, for iron filings.

It passes downward to near the bottom of the tank B', which has a bottom, H, inclined, as shown, toward the outlet-valve h', by which the sediment is cxtracted.

A tube, K', at the top of the chamber B, connects the guide-tube D with the exterior of the cylinder A.

Beneath the vessel A is arranged the carbureting'- machine O, containing within it several small boxes p p p", containing gasoline or hydrocarbon-liquid.

The hydrogen gas, air, or coal gas to be carbureted passes into one of these boxes p by the pipe K"and escapes at the bottom of the box beneath the level of gasoline. It then passes from the upper part ofthe said box, b v pipe B, into thebox p', where it receives an additional amount of carbon, and so on, in a similar manner, tobox p", Ifrom which it escapes by pipe R'to the gas-burner i The operation ofthe machine is in thismanner: y The cap Ev is unscrewed and basket G lled with iron turnings, and the ycap E screwed on tight again. rIhe upper tank B is new filled with dilute acid, which runs down the connccting-pipeM and lls the lower chamber B. The contact of the liquid and iron generates the hydrogen gas, which passes up the basket G, and out at pipe K', and into the carburetingmachine O, as previously described, from which it passes out at R to the burners in the state of carbureted-hydrogen gas.

VVheu the gas-lights are turned out, and the pressure of the gas becomes too strong, the liquid is forced up the pipe M into the upper chamber B, out of contact with the basket G, and no more gas is generated. The stop-cock N may now be closed, and the liquid retained in the upper tank B, while the sulphate and residuuln is drawn off at the outlet h'.

By this construction I avoid the drawing otl oi the liquid on every removal of the deposit.

I use the carbureting-rnacl1ine O as a base or stand -for the cylinder A. It is not, however, essential they should be so arranged. They may be arranged, as shown in g. 3, at some distance apart, the carbureting-machine in the yard and the hydrogen-machine in the cellar, as may suit convenience or safety.

By this construction of machine, when the cock N is closcdthe liquid is retained in the upper chamber nntil properly mixed. The cock is then full opened, and the liquid falls into the lower chamber. If too much gas is generated, the liquid passes back into the upper chamber by the pressure of' gas upon it. In this manner it passes from chamber to chamber ac cording to the number of lights required.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The pipe M and stop-'cock N, arranged so as to connect the upper reservoir B with the lower generating gas-chamber B, that the dilute acid passes from the chamber B to the chamber B', and back again from the lower to the upper according to the pressure ofthe gas, substantially as herein described.

` 2. The arrangement of the basket G passing through the guide-tube D. within the chamber B, into the lower chamber B', for the purpose herein detcribed.

3. The arrangement of the guide-tube D, outletpipe for` gas K', and basket G, in combination with the chambers B B, substantially as herein described.
